I have been using the PP Buy it Now buttons on my website with full IPN integration for years and it has worked fine. Now I have written a new cart and want to use express checkout and send multiple items in one transaction. I have all this working and it sends it to PP and I see a PP page with the items down one side and the Login or pay with card details in the middle. The problem is that the login does not accept any username\password combo I try. I have tried this with my own login details, which admittedly are the same as the account I am trying to pay, but it doesnt say you can't use this account. it returns an invalid username or password. I have also tried this with an unconnected friends account but this failed in the same manner. I have tried in both Sandbox and live configs, remembering to change the account details in the sent variables and the IPN listener code each time. Does anyone have any ideas? Regards CG
